[Announce unto them:] "Go, then, [freely] about the earth for four months -but know that you can never elude God, and that, verily, God shall bring disgrace upon all who refuse to acknowledge the truth!"

Go ye, then, for four months, backwards and forwards, (as ye will), throughout the land, but know ye that ye cannot frustrate God (by your falsehood) but that God will cover with shame those who reject Him.

Travel freely in the land four months, and know that ye cannot escape Allah and that Allah will confound the disbelievers (in His Guidance).

So go about in the land for four months and know that you cannot escape Allah and that Allah will disgrace the disbelievers.

So travel freely, [O disbelievers], throughout the land [during] four months but know that you cannot cause failure to Allah and that Allah will disgrace the disbelievers.
